Case Airflow Direction. Suggestions?

Hey guys,

I'm new to the forum, looking for some advice in regards to case airflow. So I understand that negative pressure (more exhaust) is good for cooling but will attract dust and positive pressure (more intake) is good for dust reduction.

 

So here is my setup:

Thermaltake V4 Black Edition

Geforce GTX 550 ti

Thermaltake tr2-600 600 watt psu

Intel i5-750 quad core (95 watts)

w/Arctic Cooling Freezer 7 Rev 2

 

ONLY 1 REAR EXHAUST CASE FAN.

 

So I have attached the picture of my current setup, I picked up some brand new case fans because the ones in my case have become noisy

I just picked up the 550 ti a few weeks ago from a friend and I have noticed my PSU fan has begun to spin abit quicker than id like, so therefore I am replacing the fan inside the PSU with a new one! Hopefully it will be much quieter. 

 

Does anyone have any suggestions on changing the arrangements of fans in the case? My priorites are NOISE, DUST and Cooling in that order, I do NOT OC at all, nor play games and nor do I do video editing of any sort. 

 

I do not have any intake fans, just exhaust and I have to option of placing intake fans at the side, front or bottom. Should I add an intake fan and hope that makes other fans run at a lower speed due to increased cooling?

 

Also my computer does get quite dusty, even on top of the exhaust fan for the CPU cooler.

 

One idea of mine was to reverse the rear case fan to INTAKE (blowing right at the cpu) and purchase a passive/large heatsink for the CPU in attempt to decrease noise, would this be enough cooling?

 

Thank you so much

 

Please not the red arrows are exhaust and blue are intake. The PSU and graphics card shares an intake port without a fan on the side panel.

CABLE MANAGEMENT!

 

Seriously though... You could zip tie those wires; get some more righteous, and open area for the air to go through. 

 

Like by your HDD bay! All those wires block air from moving freely in there.

 

Do you have a side fan? Exhaust on intake?

I think a spider made a web of cables in your case...

Intakes to side and front, cable management. Flip PSU around to get fresh air from bottom. Now it competes with GPU and that is more reason to fan getting louder. No real need to change it and possibly damage it. You can make rear intake but I would put two top exhausts instead.

You guys are too funny. Yes my case lacks cable management. I will fix that right away.

But I understand that adding more fans would mean a louder system which is certainly not what I want. And flipping the psu might be an option but I would assume I need a dust filter for the bottom.

Ideally I want to stay at one fan or at most increase to two fans in total.

Thanks

Well, noise level depends on so many things. You need to figure what is loudest you can stand and find fans/fanspeeds that are better than your limit. But if you want to keep system just something like 3 fans then set two as intakes and one exhaust. But generally there's always something louder than fans, even in idling system.

 

A for PSU, that is filtered already. As is front fan mount. For side/bottom you need to get filter but those are pretty cheap.

More fan mean they have to run faster less fans mean the can run slower. slower = quieter and faster = louder

HELP! I dont know what happened by I swapped the power supply so it takes air in from the bottom. I used a compressed can of air to clean my PC and organized the wires. NOW MY CPU IS HEATING UP it says in the bios. 

 

It says my CPU runs at about 60C at idle, I didnt even touch the CPU and it was fine before! I felt the area around the CPU and its not warms, it seems actually colder than usual. Could my bios be incorrect? The CPU fan is running full blast, to be honest it doesnt feel hot at all.

 

Thanks PLEASE HELP!

Gah what is wrong... Temperatures began to shoot up to almost 100C at random from 50C at idle within seconds. It says cpu usage is super high as well but in fact there are no heavy processes open. I took of the back panel of the case to feel the temperature of the CPU at the back and indeed it was blazing hot... So the sensors are working...

I did use compressed air, perhaps I got dust lodged somewhere in the heatsink?

Ugh why did I bother with trying to reduce noise. Now my PC is unusable.

Reseat cooler. Just in case. There shouldn't be anything wrong with some cable management. Is CPU fan spinning right?

 

More fan mean they have to run faster less fans mean the can run slower. slower = quieter and faster = louder

 

Don't you mean other way around? More fans = less speed = quieter and less fans = more speed = more noise? But ofc one has to set them to run at certain speed.

Basic rule of thumb: Take fresh air in through the front, side, and bottom, then exhaust the air out the top and back.

I have this exact case at home. I threw in an intake fan in the front (I think it only supports a 120mm fan, I don't remember as I'm on vacation), a side panel intake fan, made my PSU an intake, and one rear exhaust fan. I'm only using one rear exhaust fan to keep positive air pressure in the case so I don't suck dust in the cracks an crevices. I think it's one of the best ways I could do it in the case. I tucked all of the power cables I didn't used under My HDD as it was on the 3 slot from the bottom. I can post a picture of my case if you'd like when I get home tomorrow, as I will be rebuilding my PC in a Define R4 that I won in the case contest thing they held  :)

Cable management here isnt going to make the difference. The cables blocking a part of your fan isn't going to effect your airflow or temps, you just end up with a low pressure on one side thats it.

Also are you sure its in Celcius? Because the Tjmax is 99° (http://i.imgur.com/hru11.png) for this cpu so you can't have your pc running at this temperature because it would instantly shut the pc down.
